Mass arrests and anti-coronavirus restrictions on public gatherings have largely halted the protests this year.
In recent weeks, renewed clashes have broken out after Beijing announced plans to impose a sweeping national security law over the restless city and last week tens of thousands defied the government to mark the anniversary of the Tiananmen crackdown.
Nok has since restarted work as a carer, a job that gives him more flexible hours — and pays better than nursing.
But he says he is ready to return to the streets at any time, keeping his equipment in a cupboard.
Inside is a yellow hi-vis jacket with the word “Medic” emblazoned on it, a helmet and respirator, a bag stuffed with gauze, bandages, antiseptic creams and the saline used to wash the eyes of those struck by pepper spray and tear gas.
“I’m a professional nurse and I need to give the injured appropriate treatment,” he said as he checked supplies.
Walking through the streets of Tsim Sha Tsui, a shopping district that saw frequent clashes last year, Nok found it hard to work out what, if anything, had been achieved by the protests.
